[Want to know] Javascript code that clicks all "add a friend" buttons at once.

Greetings!

Usually if you wanted lots of friends, you found a list of people who have liked a Page and then manually click each fan individually for a friend request. Now there used to be a code that you entered from a Chrome Console that clicked all the buttons at once.

Does anyone know a working code that clicks the similar friend request buttons at once?

You will get your account banned soon. Also i don't think this types of Javascript is available.
Thanks
